ASUS DirectCU II Updated Lineup: NVIDIA GTX 700 Series Edition

Author: Josh Walrath
Manufacturer: Asus

Results: Luxmark

I was quite curious about the OpenCL performance of these latest cards.  AMD has really been pushing OpenCL as of late, especially in advance of the release of the Kaveri APUs.  They have a pretty solid OpenCL 1.2 implementation for their GCN based chips.  NVIDIA of course has been blowing the GPGPU horn as loudly as possible over the years and focused on CUDA.  Oddly enough, Kepler made compute performance take a back seat to enable better performance and efficiency in graphics applications.  I used the 64 bit version of Luxmark 2.0 with the Sala test.

If there was one weakness for the NVIDIA GTX 700 series (Kepler), it is GPGPU type applications.  Luxmark is OpenCL based and not a native CUDA application.  The 8 thread Intel i7 3770K easily outperforms the lower end NVIDIA models, while the R7970 blows everything out of the water in this particular benchmark.  NVIDIA really pushed gaming performance with this architecture, and GPGPU type applications took a backseat.

The fact that every card has a new cooler except for the GTX 770 really irritates me...

It is a new cooler on the GTX 770, because the previous GTX 680 had the triple slot number.  It is unfortunate that they did not update the shroud though to match those of the 780 and 760.

Great cards these GTX780 Direct CUs. I've been a little hasty on getting the MSI GTX690 reference card early this March (got a great discount on it though :-) . It's not overclocked (for acoustic and temperature reasons), but on a 60Hz 1080p SAMSUNG monitor displays everything beautifully, with all eye-candy maxed out. Constant 60FPS with V-Sync on for great image quality - that is on every game I played so far. No need for overclocking yet! If I hadn't bought this GTX690 beauty, I most definitely would have gone for ASUS's GTX780. Thanks for this review, Josh. Great job. All the best!

PS: Might wanna check Min/Avg colour bars on Unigine Heaven benchmarks page.

I had just gotten one of these card myself and I have had problems with it. It goes unresponsive. As soon as I put back in my gtx 680 no problems so i was wondering whether it was the card so i wend and returned it and the next one did the same thing. So I had my friend let me borrow his GTX 770 this was a EVGA version I put that thing in and I had absolutely no problems what soever so keep this in mind.
